At least four people died** when a small boat carrying migrants from Turkey sank in the Aegean Sea off Samos, Greece. Five others were rescued, but it's unclear if more are missing. The boat, believed to be a dinghy, sank for unknown reasons, and authorities are searching for survivors. This is a common route for migrants trying to reach the EU, often in flimsy inflatables or powerful speedboats. The victims' identities and nationalities are not yet known. Greece has seen a surge in migrant crossings despite a crackdown along the Turkish border.
